WEATHER STRIP.

Application tiled August 2, 1926. Serial No. 126,624.

\ doors and windows for the purpose of excludin drafts, dust and rain, and preventing said doors and windows from rattling.

Another object is to provide resilient parting strips which coact with the weather i strips in excluding drafts, dust and rain,

and preventing the sash from rattling.

A further object of my invention is to provide spring means for assisting in raising the window sash.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing,.in which:

Fig. 1 shows the invention applied to a pair of window sash.

Fig. 2 is an enlarged fragmentary cross section on line 2 of Fig. 1.

Fig 3 is an enlarged fragmentary vertical sectionon line '3--3 of Fig. 1.

Fig 4 represents one section of the window strip ready for assembly.

Referring in detail to the different parts, 2 designates a housing which is preferably in the yform of a channel bar. 4 designates a rigid bar preferably of hollow rectangular cross section and adapted to fit loosely within the housing 2. 6 designates a plurality of springs adapted to be interposed between the housing 2 and the bar 4 to press the latter f outwardly against the window i frame C.

In order to, -install the weather strip grooves 8 are 'formed in the top and side rails of an' upper sash as A, while similar grooves are formed in the bottom and side rails of the lower sash B to receive the housings 2, which are fitted snugly within said grooves. y,The bars 4-with the springs 6 assembled upon fastening devices 10, such as screws or nails are then placed within the housings 2, which have holes to permit the fastening devices 10 to be driven into the sash and thus hold the housings 2, the Ybars 4 and the springs 6 in assembled position. When thus installed it is apparent thatthe springs 6 will press the associate bars 4 outwardly againstthe adjacent surfaces of the window frame C and thereby exclude dust and rain and prevent the sash from rattling.

In order to prevent the heads of the nails or screws 10 from contracting the adjacent the sashes A and B to assist in raisin portions of the window frame C, the outer holes 12 provided in the bars 4 for said nails or screws 10 are of sufficient diameter to allow the heads of said nails or screws to be drlven inwardly against the inner portions .of said bars 4, as shown more clearly by Figs. 2. and'4. The joint between the meeting rails D and E of the sash A and B, respectively, may be also rendered rattle andweather-proof by supplying one of said meeting rails with a weather strip, as shown by dotted lines Fig. 1, and full lines Fi 3.

.The joints between the side rails o the window sash A and B and the adjacent portions of the window frame C are' further rendered rattle and weather-proof by parting strips 14 consisting of resilient channel bars which are installed in grooves 16 in said .frame C and have their free ends 18 pressing against the sash A and B.

In lieu of the ordinary sash cords and weights for counterbalancing the weight of the latter, I provide coil springs 20, whic are arranged in grooves 22 and 24 in the side rails of the sash A and B and secured at their lower ends to the respective sash by suitable fastening devices 24 and at their upper ends to the frame Cthrough the intermediary of suitable fastening means such as screw eyes 26.`

While I have shown and described the preferred construction and arrangement of i my invention I reserve the right to all such changes and' modifications as properly fall within the spirit and scope of the invention as claimed. i y

Having vthus described my invention, what I claim and desire to secure by Letters Patent, is:

A device of the character described consisting of channel bars of the saine length as and adapted to be installed in grooves formed in edges lof the window sash, bars of hollow rectangular cross section movably mounted in said channel bars, spring means interposed between the channel bars and said rectangular bars to force the latter against the window frame, and meansy for holding said bars and said spring means in assembled positionl in the window sash consisting of a plurality of elements extending loosely through the rectangular bars and the channel bars and firmly secured in the window sash.

In testimony whereof I aiiix my signature.
